T 0 all whom it may concern Be it known that I, EUGENE SCHNEIDER, a citizen of the Republic of France, and a resident of Paris, France,have invented new and useful Improvements in Guns Mounted on Wheeled Carriages, which invention is fully set forth in the following specification.

Wheeled gun carriages are known which are so constructed as to provide a limited range of lateral movement on the axle between the supporting wheels for the purpose of varying the training of the gun. In such carriages, the lateral movement is obtained by the operation of a' screw journaled in the carriage and working in a nut fixed to the. wheeled axle to slide the carriage along the same in either direction.

.According to the present invention, the head of the gun carriage, instead of sliding upon the wheeled axle, is slidably mounted on an auxiliary or false axle that is vertically movable in relation tolthe main or wheeled axle, the auxiliary axle being elastically suspended from the main axle by in terposed springs that are utilized for transport purposes. In this instance, the auxiliary axle comprises a tubular sleeve mounted on the main axle, the interior diameter of thetubular sleeve being considerably greater than the exterior diameter of the main axle so that the auxiliary axle can move vertically-relatively to the main axle. hfeans are provided for relieving the springs of the toad andfor connecting the auxiliary axle directly with-the mainaxle to form a rigid bearing between the two axles so" that the shock of dischargewill be transmitted directly from thecarria'ge to the main axle during firing without the interposition of the springs. H I

In" my copending application: filed Octo ber 24, 1919, Serial No. 333,101, several eon; struc tional' forms of this invention are diselosed,and the present application is'a d-i vision of the earlierapplication, being direoted to one of the constructional forms therein shown and described.

In the accompanying drawings, in which similar reference characters designate corresponding parts- Figure l is a view, partly in elevation and partly in vertical section, of a constructional form of the invention;

Fig. 2 is a sectional view on the line 2-2 of Flg. 1.

According to this, constructional form of the invention, the straight main axle A, in tubular form, is carried by the wheels B in the usual manner Around the main. axle ispla ced the auxiliary or false axle F also of tubular form: Theinterior diameter of the auxiliary axle is considerably greater than, theexterior diameter'oit' the main axle so that the former can have considerable transverse play in relation to the latter. Slidable laterally on the auxiliary axle is the gun carriageC, the latter being adjusted on the .formerI by a screw (not: disclosed herein, but fully shown in Figs. 2 and .4 of the parent case and. described therein) journa'led in the carriageand engaging a nut on the auxiliary axle.

Inter-posed between the. main and; auxile iary axles at each endthereof is the leaf spring I, the upper and lowenbowsof which are connected by the links. H;. The lower bow of the spring is mounted: in the upper endof the block G seated atits'lower end on the main axle between collars thereon to prevent movement ofthe. block longitudinally of. the axle. The block extends: up: wardly frolnithe main axle through the wall of the auxiliary axle, having free vertical playithereul; Asth'e block is' held against longitudinal movement on the main axle, it, in turn, holds the auxiliary axleagainst suchmovement and acts as; a guide for the two axles in their relative. vertical niovementj The upper bow of the: spring I is seated in the'upner end of t'he stirrupi or. housing 0. extending downward on opposite sides of the block G. and-encircling-at' its lower end thea uxiliary axle; In this way; the two" springs I are interposed b'etweenthe two axles to" support: the load of the carriage in elasticsuspension so thatthe jars and jolts. impar ed to the: wheels Bin traweling over a rough road will he-ab sorb'ed by' the sprincs airdnot transmitted to the carriage Turned into the-head 0 of" each. housing 0- is the vertical screw L passing" through the upperbow of the spring I and carrying at the lower end the plate K. By turning the screw into'th'e' housingqthe plate. K can beiorced down onto the top of the block G. With the plates K so positioned, rigid bearings are formed between the two axles so that in firing the shock, of discharge will be transmitted from the carr age C through the auxiliary axle F, the housings O, the screws too L, the plates K and the blocks G to the main axle A without the interposition of the springs I.

In placing the gun for firing, the tail of the carriage trail (not shown) is pivoted to the ground in the usual manner. narily to firing the bolts L are turnd down to force the plates K onto the blocks G carried by the main axle A to form a direct bearing between the carriage and the main axle and thereby relieve the springs of the load. In training the gun, the head of the carriage is moved along the auxiliary axle F to the desired position. During this adjustment of the carriage head, the carriage, as

a' whole, pivots on the anchored tail of the V trail. As the gun is so trained, the movementof the carriage head along the auxiliary axle will cause a slight shifting in the position of the main axle relatively to the trail pivot and the supporting wheels B will turn slightly to accommodate this shifting of the main axle. Preliminarily to transport, the carriage head is moved to midway position on the auxiliary axle and the bolts L are turned upward in their housings to raise the plates K from the blocks G, thereby interposing the springs I-between the two axles to carry the load.

What is claimed is:

1. In a gun mounting, a wheeled main axle, a tubular auxiliary axle around the main axle having vertical play in relation to the same, a carria e slidable along the auxiliary axle for training the gun, and spring mechanism interposed between the two axles to carry the load of the carriage during transport. w

2. In a gun mounting, a wheeled main 'main axle, a tubular auxiliary axle around the main axle, the interior diameter of the auxlliary axle being greater than the exterior diameter of the main axle to permit relativelytransverse movement between the two axles, a carriage slidable along the auxiliary axle for training the gun, and spring Prelimimechanism interposed between the two axles to carry the load of the carriage during transport.

4. In a gun mounting, a tubular wheeled main axle, a tubular auxiliary axle around and to transmit the shock of discharge from the carriage directly to the main axle.

5. In a gun mounting, a wheeled main axle, a. tubular auxiliary axle around the main axle having vertical play in relation to the same, a carriage slidable along the auxiliary axle for training the gun, a housing mounted on the auxiliary axle, a block seated on the main axle and proj eeting through the wall of the auxiliary axle to prevent relatively longitudinal movement of the two axles, and a spring interposed between the housing and the block to carry the load of the carriage during transport.

6. In a gun mounting, a wheeled main axle, a tubular auxiliary axle around the main axle having vertical play in relation to the same, a carriage slidable along the auxiliary axle for training the gun, a housing mounted on the auxiliary axle, a block seated on the main axle and projecting through the wall of the auxiliary axle to prevent relatively longitudinal movement of the two-axles, a spring interposed between the housing and the block to carry the load of the carriage during transport, a bearing plate vertically movable in: the housing, and a screw threaded in the housing for forcing the bearing plate onto the block to form a direct bearing between the two axles to relieve the spring of the load of the carriage during firing and to transmit the shock of discharge from the carriage directly to the main axle without the interposition of the spring. V

In testimony whereof I have sig ed this specification.
